BANDAGE MACHlNE.

SPECIFICATION forming part of Letters Patent 1510309511, dated December 16, 1884-.

Application tiled March 10, 1894. (X modelil To (0% whom it may concern:

Be it known that 1', El)\VARD T. TlNUlI, a citizen of the United States, and a resident of Seymour, in the county of Jackson and State of Indiana, have invented certain new and useful Improvements in Machines for Making Bandages, and I. do hereby declare that the following is a full, clear, and exact description of the invention, which will enable oth- IO ers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective view of my inn- 1 5 proved machine for making bandages, show ing the bandage-cutting attachment swung back against the side of the machine out of the way. Fig. 2 is a similar view with the curved metal. spreading-plate and the inclined slide which supports the plaster-of-paris or its equivalent removed and parts of the outer casing of the machine broken away. l1i is a longitudinal vertical sectional view taken on line a; :r, Fig. 1, and Fig. 4; is a perspective detail view of the bandage-cutting attachment.

Similar letters of reference indicate corre sponding parts inall the figures.

My invention consists in the improved construction and combination of parts of a niachine adapted for preparing or making bandages coated with plaster-of-paris or other similar material for the use of surgeons and others, as will be hereinafter more fully described, and particularly pointed out in the 55 claim.

In the accompanying drawings, A indicates the frame or outer casing of myimprovcdmachine. In the sides of this frame or casing are journaled the ends of a large roller, B, and to o the rear of and a little below this large roller a smaller roller, (l, for the purposehereinafter specified.

Upon the upper rear end of the frame A is secured by one of its extremitiesa spool-wire,

4 5 D, around which the empty bandageis wound. The bandage passes from the spool-wire down over a tension-wire, E, under the small roller 0, then up over the large roller 13, at which point the plaster-of-paris is spread upon the bandage, as will be hereinafter fully described,

when the finished plaster is wound uponaremovable shaft, F, which is journaled in the front end of the frame A, the said shaft being oval'shaped in cross-section, in order to prevent the bandage from slipping oif of it as it is wound thereon, and being provided with a handle, l by means of which it is rotated.

G indicates the inclined slide or partition upon which the plaster-otparis or other similar material rests, the said slide being sup- 6o ported upon inclined ways 11, and prevented from sliding down too far upon the same by projecting pins or studs G-,fitting into inclined notches or recesses A in the upper part of the frame A. The slide (lhas secured upon its lower end a strip, I, of leather or other suitable material, the free edge of which bears with an even and yielding pressure against the large roller B, the slide being held firmly in its operative position by means ofa catch, 1, on its lower rear side engaging with a cross bar or rod, l, in the lower part of the frame A.

ll represents the curved metal spreadingplate, the construction of which will be more readily understood by reference to Fig. 3 of 7 5 the drawings, the ripper end of the said plate being provided with projecting trunnions K,

adapted to fit within either one of the boxes or bearings, K, by which arrangement the pressure of the lower square or flat edge of So the plate upon the bandage maybe regulated, and thereby the amount of plaster-of-paris deposited upon the said bandage.

The operation ofmy improved machine is as follows: The empty bandageis adjusted around 8 5 the several roller-sand shafts in the manner previously described, the slide G and metal plate 13'. being then placed in their operative positions. The plaster-ofparis or other similar material with which it is desired to spread 0 the bandage is then placed in the space be tween the slide and metal plate. The shaft 1* is then rotated by its handle, so as to wind the bandage around itself, when the plasterof-paris in the spacebetwcen the slide and 5 metal plate will be drawn by the moving cloth or bandage up against the flat edge of the metal spreading-plate,which,accordingly as it is adjusted in its bearings,wil1 spread the plasterof-paris in. a thick. or thin layer over the band age, the surplus plasterfalling back of its own weight into the lower part of the space in which it is contained, by which arrangement the machine is made to a certain extent selffeeding.

L represents the bandage-cutting attachment, which consists of a frame,M,upon which the roll of cloth from which the bandage is to be made is placed in order to cut the said cloth of such width that it will pass through the machine. This frame is provided with an adjustable slide, N, against which one end of the roll of cloth bears, and which may be adjusted according to the width to which it is desired to cut the bandage. Upon one side of the frame is hinged by one of its ends a curved metal strip, 0, which serves to hold the roll of cloth in position 011 the frame M, and which is provided with a longitudinal slot, 0, registering or corresponding with a similar open slot, 0, in the upright portion of the frame M, the said slots forming a guide for the knife, by means of which the roll of cloth is cut into the desired width. The frame M is preferably hinged at one end to the main frame A, to enable it to be swung back against one side of the main frame out of the way after the cloth has been cut.

The above-described bandage-cutting attachment forms no part of my present inven tion, and I do not, therefore, desire to make any claim for the same.

From the foregoing description, taken in conneetion with the accompanying drawings, the construction and operation of my improved machine will readily be understood without requiring further explanation.

It will be seen that my improved machine is simple in construction,and,being devoid of all complicated parts,.is not liable to break or get out of order.

By constructing the metal spreading-plate in the manner described the plasterbf-paris will be spread smoothly and evenly on the bandage, while by making the said plate ad justable in its bearings the thickness of the coat applied upon the bandage may be regulated at the will of the operator. The shaft upon which the finished bandage is wound is 'been heretofore constructed in which the empty bandage is wound upon a suitable spool-wire, and after passing under tensionrollers and through or under a hopper in which the plaster-of-paris is contained the finished bandage is wound upon a suitable roller, as shown in the patents to F. Green, No. 196,892, and O. G. Hill, No. 209,045, and I do not, therefore, claim such construction, broadly; but

What I claim as my invention, and desire to secure by Letters Patent of the United States, is-

As an improvement in machines for making plaster-of-paris bandages, thecombination, with asuitable outer frame or casing, of aspoolwire upon which the empty bandage is wound, a tension-wire, and small roller under which the empty bandage passes, a large roller over which the bandage is drawn to receive its coating of plaster-of-paris, an inclined slide provided at its lower end with a strip ofleather or othersuitabie material adapted to bear against thelarge roller over which the bandage passes, a curved adjustable spreading-plate having a lower straight edge adapted to bear upon the upper side of the large roller, and a removable shaft, oval in cross-seetion, upon which the finished bandage is wound, all constructed and arranged to operate substantially in the manner and for the purpose shown and described.

In testimony that I claim the foregoing as my own I have hereunto aflixed my signature in presence of two witnesses.
